To continue, click on the image that you think best represents how DNA normally
looks in the cell. - Answer -First image
Looking at the images, how many chromosomes are there in a typical human? -
Answer -46
What do you notice about the chromosomes in both images? - Answer -They come
in pairs
Why are chromosomes a poor way to think of how DNA is normally stored? -
Answer -DNA only looks like this during replication
The top image, called a karyogram or karyotype, is from a human female, while
the bottom one is from a human male. What major difference do you notice? -
Answer -The male has a set of mismatched chromosomes
Thinking back to what you learned about genetics, what do the colored bands on
the chromosome represent? - Answer -Genes
What do the images pointing to each colored band represent? - Answer -
Phenotypes
From your exploration of DNA structure and biological macromolecules, what do
you recall is the function of DNA in the cell? - Answer -Information storage
